数字频率调制又称频移键控（FSK），二进制频移键控记作2FSK。数字频移键控是用载波的频率来传送数字消息，即用所传送的数字消息控制载波的频率。2FSK信号便是符号“1”对应于载频，而符号“0”对应于载频（与不同的另一载频）的已调波形，而且与之间的改变是瞬间完成的。 -Digital frequency modulation called frequency shift keying (FSK), binary frequency shift keying recorded as 2FSK. Digital frequency-shift keying is the carrier frequency to transmit digital information, that is, the number of messages transmitted with the control of the carrier frequency. 2FSK signal is the symbol of "1" corresponds to the carrier frequency, while the symbol "0" corresponds to the carrier frequency (with a different carrier frequency to another) and modulated waveform, but also between the change was instantaneous.

一个AD9851的驱动。用的并行时序。 现在把程序和电路图发上来，大家帮帮我看看问题出在那里。谢谢了。 要是有做成功的能共享一下电路和程序感激！ main.c -An AD9851 driver. Timing used in parallel. Now that the procedures and schematics hair up, everyone help me to see the problem there. Thank you. If success has to do to share about the circuit and procedures grateful! main.c

用传输矩阵法计算一维光子晶体的带结构的程序,用matlab所编,文件解压后,程序写在word文档中,并附有在matlab下画的图,本人感觉非常有用-use of the transfer matrix method one-dimensional photonic crystal with the structure of the program, prepared by Matlab. unpacks the files, procedures written in word document, together with the painting under Matlab plans, I feel very useful

这有一点C的资料，看看，喜欢的下载吧，帮忙-C
